Final answer:
False. Parsing input that the logic of the program execution can still introduce vulnerabilities that can be exploited to execute arbitrary code.
Step-by-step explanation:
False. When a program's stack or heap space is protected, it means that it has security measures in place to prevent unauthorized access or execution of code in those areas of memory.
However, parsing input that the logic of the program execution can still introduce vulnerabilities that can be exploited to execute arbitrary code. One example of this is a buffer overflow, where an input that is larger than the allocated memory space causes a program to overwrite adjacent memory, leading to unexpected behavior and potential code execution.
